改良四通路玻璃体切割在人工晶状体后脱位治疗中的应用

摘要

目的:报道改良四通路玻璃体切割术治疗1例后房型人工晶状体后脱位.方法:一位青年性白内障患者,双眼白内障术后均发生人工晶状体后脱位,其1眼应用改良四通路玻璃体切割技术将人工晶状体复位,另1眼应患者的要求而未行手术治疗.结果:术中和术后未发生任何并发症,患者术眼视力迅速回复,术后14 mo最佳矫正视力为0.5;而未行手术治疗的另1眼发生全视网膜脱离,仅残余手动视力.结论:改良四通路玻璃体切割术是治疗人工晶状体后脱位的一个好选择.%AIM: To report the use of modified four ports pars plana vitrectomy in managing a dislocated posterior chamber intraocular lens.METHODS: A young man with bilateral pseudophakia and dislocated PC-IOLs had undergone modified four ports pars plana vitrectomy in relocating a dislocated posterior chamber intraocular lens. This procedure was surgically less tedious and demanding compared with previous methods of IOL retrieval.RESULTS: No significant intra- or post-operative complication was noted. The visual recovery of the operated eye was rapid with the best corrected visual acuity at 14 months post-operation being 0.5. In contrast, the right eye without operation due to patient refusal developed total retinal detachment with hand movement visual acuity.CONCLUSION: Modified four ports pars plana vitrectomy may be a more ophthalmic surgeon friendly alternative in the retrieval of dislocated IOL.
